Do you need external mastic in Stormontfield?
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint.
Common reasons people contact us are:
- Hard, crazed mastic that has stopped moving
- Sealant pulling away from one side of the joint
- Plants rooting in failed movement joints
- Joints with sealant missing in places
If you let a flat or house near Perth station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- How long the guarantee is
- Is VAT in the price?
- Which colour the sealant will be
- How much experience the applicator has
About our external mastic in Stormontfield
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. We work on concrete & block, façade panels and joints between brick and frames, and common reasons people get in touch are rigid filler in a joint that should flex and leaking joints around cladding and façade panels.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
Your job is guaranteed for a year, as with all our work.

Outside joints around Stormontfield
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
Schools such as Bertha Park High School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

What we can’t put right
It helps to know what we can’t do:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Render that’s blown, hollow or coming away
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.
Where we work in Stormontfield
- Concrete & block
- Joints between brick and frames
- Brickwork movement joints
- Façade panels
- Render & cladding joints
- Copings & trims
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Keep high-pressure jets off the joints
- Fix overflowing gutters above sealed joints
- Show decorators and builders where the movement joints are
- Act on the first splits you see
Do not paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
How the job changes by surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.

Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you use backing rod?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Do you have insurance?
Yes, we’re fully insured.
What is a movement joint?
Brickwork, render and cladding all move a little, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
